Mathematics

padilas [110]3 years ago

Answer:

The volume of this given solid figure is 18 cubic units.

Step-by-step explanation:

Here, given the volume of 1 small cube = 1 cubic units

Now, counting the total cubes in the given solid figure, we get

Number of cubes in base row = 10

Number of cubes in middle row  = 6

Number of cubes in top most row = 2

So, the total number of cubes in the figure  = 10 + 6 + 2 = 18 cubes

So, the volume of 18 cubes  = 18 ( Volume of 1 small cube)

                                              =  18 x (1 cubic units)  = 18 cubic units

Hence, the volume of this given solid figure is 18 cubic units.

In a parallelogram whose area is 15, the base is represented by x+7 and the altitude x-7. Find the base of parallelogram.
Sati [7]
Area = (base)*(height)
15 = (x+7)(x-7)
(x+7)(x-7) = 15
x^2 - 49 = 15
x^2 - 49+49 = 15+49
x^2 = 64
sqrt(x^2) = sqrt(64)
x = 8 ... note that x can't be negative

If x = 8, then the base is...
x+7 = 8+7 = 15

Therefore the base is 15 units. 
(the height is x-7 = 8-7 = 1 unit)

A 16- fl oz bottle of juice cost $2.00. What is the unit cost ?
Dmitry [639]

Answer:

$0.13 (this is a rounded answer)

Step-by-step explanation:

The unit cost is the cost of a 1 ounce bottle so you would divide the cost by the total number of ounces:

$2.00 divided by 16 is 0.125 but you would round because you need a cost not a decimal.

So your final answer would be $0.13 per ounce.

Let f(x) = 6x2 + 5 and g(x) = 3x - 5. Find g(f(0)).<br> A) 10 <br> B) 75 <br> C) 90 <br> D) 155
alisha [4.7K]

Answer:

A) 10

Step-by-step explanation:

let x =0

f(0) = 6(0)^2 +5

f(0) = 5

now put 5 into g(x)

g(5) = 3(5) -5

g(5) = 15-5

g(5) =10


so g(f(0)) = g(5) = 10
